Naruto would probably be very friendly and kind. He has a big heart, so he'd likely greet her with a big smile and start chatting right away, asking her name and where she's from.
Sakura might be really surprised at first. She could offer to help Naruto with his girl disguise, teaching him things like how to do his hair or choose the right clothes. She might also find it a bit funny but would be supportive in the end, seeing it as part of a mission. Sasuke, on the other hand, might be a bit more aloof. He would probably just raise an eyebrow at Naruto's new look but wouldn't make a big fuss about it as long as it was for a good reason.
Ino might be initially shocked. But then she'd probably be quite excited. She could start planning all sorts of things to do with Naruto, like shopping for new clothes or teaching her about girl - only ninja techniques. Ino would likely see it as an opportunity to have a new kind of friend.
Neji might get angry. He's a proud character, and being called a girl in a somewhat derogatory way (if that's how he takes it) could make him lash out at Naruto. He could give Naruto a cold stare and tell him to watch his words.
His friends' reactions would vary. Hinata would be really happy for Naruto. She would be gentle with the little girl and offer to make her clothes or cook for her. Kiba might be a bit skeptical at first, thinking Naruto might not be fully prepared for raising a child. But when he sees how much Naruto cares, he would be more accepting. Choji would probably be excited and share his snacks with the little girl right away, showing his warm - heartedness towards Naruto's new family member.
Sasuke might be initially shocked. But being Sasuke, he would probably keep his thoughts to himself at first and just observe Naruto's new behavior. Later, he might offer some dry comments or advice if he sees Naruto struggling with the changes. Sakura, on the other hand, would be very curious. She might try to help Naruto adjust, like teaching him how to do a girl's hair or choose appropriate clothes, while also being a bit envious if Naruto starts to get more attention from the boys in the village.
The ninja in the village, like Kakashi, would need to figure out how to handle this situation. They would have to ensure Naruto's safety while also trying to find a way to reverse the transformation. They might also have to deal with any potential threats that come as a result of Naruto's new form. For example, if other villages heard about it, they could try to take advantage of the situation.
Kakashi would likely be amused by the whole situation. He might give Naruto some tips on how to blend in better as a girl, using his own knowledge of disguise techniques. Iruka would be more concerned about the reasons behind Naruto dressing as a girl and would make sure Naruto is comfortable with it. He would also be there to support Naruto if any of the other villagers had a negative reaction.
As for Shikamaru, he would probably find the whole situation too troublesome. He might avoid 'female Naruto' at first, but then when he realizes it's really Naruto, he would start to give advice on how to handle the situation in the most efficient way, like how to avoid unwanted attention from other guys.
Sakura might be really surprised at first. She could be a bit skeptical about whether it's really Naruto or some kind of trick. But then she would probably try to help him find a way to change back.
